One of the most significant advantages of HDG tanks is their longevity. The zinc coating provides a barrier that protects the underlying steel from moisture and oxygen, which are primary catalysts for rust and corrosion. According to industry standards, a properly galvanized tank can last up to 50 years, making it a cost-effective and sustainable choice for storage solutions.

Secondary treatment focuses on biological processes to degrade organic matter. This is accomplished through aeration tanks, where microorganisms are introduced to consume organic pollutants. The most commonly used methods in secondary treatment include activated sludge systems and biofilm reactors. These processes can significantly reduce the biochemical oxygen demand (BOD) and total suspended solids in the water.
